Informing one's in-laws about one's past

Q: I have been married for a few years and have children. When the wedding talk was happening, my in laws to be were told that my dad married twice and has children with both wives. They reacted negatively and almost used this reason to stop the talk. Due to their negative reaction, I didn't disclose that my mother was married before and has two children from her previous marriage. But after the wedding I only told my husband. Now, I'm scared of telling my in laws as they are very old fashioned and traditional. I am still in contact with my half-siblings (I'm sure their feeling are hurt by this). What is the Islamic ruling in this situation. I have no secrets from my husband.

Stray thoughts

Q: I am so lost I cry everynight for guidance for a little sign from Allah and I beg Allah to help me but nothing ever happens. I begin to wonder if, when you die, that's it, the end. What if Allah is not there but somthing else is?

Also, would you advise to stop watching videos online as they have misguided me and my iman before.

Premarital relationship

Q: When I was a teenager I liked a boy who was very religious and knowledgeable both generally and islamically, So I told about this boy to my family. And we got engaged. He saw me once. And he liked me a lot since then. We talked very rarely and it’s only about our marriage preparations. But we couldn’t get married that year so he flew abroad for his studies. I haven’t heard any news from him since then. And I waited for the holidays so he will comeback. I believed I was engaged. But then I heard from one of his relative’s sister that he nullified the engagement and I didn’t know what the reason was behind. I got many proposals at the same time from religious students of Islamic knowledge backgrounds. But yet I found very uncomfortable to accept other proposals. Because it hurts me a lot and a lot. Though I haven’t had any premarital relationship with him, but I don’t know I liked him very much and his personalities. I mailed him because I want to know what the reason was behind, and told him it would be very difficult for me to get married with some other, because I liked him very much. But I didn’t hear from him. So I accepted one of his friend’s proposals and got married. but the i heard from one of my friends that he was quite upset for letting me go. (my friend knw this from her husband) I tried so hard to forget about that boy but yet I find so uncomfortable with those feelings. My husband knows my past because he was a close friend of him. But my husband didn’t know what I’m going through with the pain inside my heart. I don’t want to ruin my life for a person who had no interest in me. I prayed Allah a lot to help me to forget him. And I tried my best to give my husband’s rights. But sometimes I get upset for knowing the boy I liked was more knowledgeable and a hafiz unlike my husband. The boy also got married one of my friends, and I feel how lucky she was although I make dua for them whenever shaitan used to whispers me. I fight with these uncomfortable feelings so hard for nearly 4 years of my marrige but sometimes I feel weak. Please advice me to get out from this pain.
